We spend hours and hours, taking the best photographs we can, and when we finish – we apply special techniques for with a special editing software to enhance what we originally saw. When we finish, we try to save in the correct format for preservation image for the best possible way, but most people have no idea what the differences.
The three cases of a major digital camera uses to store their digital images are JPEG, TIFF and RAW formats. We must understand that these image formats and digital properties – only then will we be able to obtain a high quality photography.
The first format, and one used in graphics and photography often is the JPEG – A standard method commonly used image compression. In fact, most photographers use as their primary image. One of the main reasons is because it can be used right out of the camera, unedited, as it is considered Use as a strong premium image. It also transfers easily through the Internet, and as attachments. Plus it is writer fastest since the buffer memory camera memory card storage.
On the other hand, it is not as clear as the camera as TIFF or RAW modes, and each time the JPEG is handled more than once or twice, it will eventually become unusable. But more than that, every time the JPEG image is changed and saved again, it will lose more data.
PEG stands for "Joint Photographic Experts Group ", named after the Joint Committee which was established in 1986. The JPEG format (file extensions. Jpg with. Jpeg,. Jfif, jpg.,. Jpg and. JPE) format provides for lossy compression of images, which means that when data is compressed and then decompressed, the data is decompressed may be different from the original. However, it is sufficient to be useful in one way or another.
JPEG / JFIF is the format that is used when images are stored and transmitted over the Internet. It is preferred over GIF, which is limited to 256 colors that are not enough for color photographs or PNG, which produces larger image files.
But then, as many photographers use TIFF as their primary use. The TIFF is a file format used to store images such as line art and photographs, developed by the company Aldus, now Adobe Systems and Microsoft. A popular format for color images of high depth, it is supported by many image editing programs like PageMaker, QuarkXPress, Adobe InDesign, Photoshop, Paint Shop Pro, etc. It is extremely high image quality, with excellent compatibility with the houses editing.
TIFF can be modified and saved again with the images used countless times without throwing all the data image. Plus the image is extremely useful because it does not require software post-processing during or after its download from the camera. It is a flexible and adaptable, with an advantage for any loss image, which makes it acceptable for the publishing industry.
Compared RAW format, it uses less storage space and is adapted to change any software photo-editing. A major drawback is its very large file size, yet small choking mailboxes. During the photo shoots, memory cards are needed if using images TIFF, but the images can be taken with the same amount of memory space.
The RAW format is an image where the camera has been absolutely no change, the files are not processed or ready to be used with any editor, etc. Not a very large number of professionals use this mode, other than the purists of the camera or bizarre article writers website. So it is manipulated, the image must be treated and converted into an RGB format that is either TIFF or JPEG. This means that each pixel has been captured by the camera is now on the image.
You can now download this image on your computer for processing. Its advantages are that a huge amount of control over the final appearance of the image is yours. In addition, all the original details, stays in the picture for all the treatment needs to come.
However, When you do, you will notice that this is an image very large, probably a few MBs. This means that you will need a very large storage area or memory space if you shoot images in RAW format. Your advantage is that you can focus, size, or crop the image without losing any When image quality.
But your disadvantage is file size. You can not pass easily because it needs high connection bandwidth. Also, you can take pictures very rare, if you select RAW mode. After that, you must change the memory card or to Instead of erasing some pictures. In addition, this method is not generally accepted by the publishing industry because it produces an image 12 bits. The photographer needs to be amended by using a photo editor before submitting it for publication.
Global, if the photographer wants to keep all data the original image that was recorded, the image must be saved in RAW format. It's the closest thing we will be able to see a film negative or a transparency that the digital camera can do.
